The utility model relates to the technical field of pull devices, and in particular, to a pull device fixing apparatus and a pull device using same.

BACKGROUND

At present, people are pursuing a healthier lifestyle. Accordingly, a pull device, a new-era fitness product which is lightweight and portable and can be used anyplace and anytime for exercise, is favored by people.

The Chinese patent (CN201920905356.8) discloses a fitness pull device, which uses a motor as a force generation apparatus, where the torque controllability of the existing motor is combined with the structure of the pull device such that the magnitude of a force can vary according to an actual use requirement of a user, to enrich fitness experience of the user and achieve a better effect; moreover, the fitness pull device has a lightweight and portable structure, which is convenient for carry in travel.

In the above solution, an outer end face of the housing is provided with a buckle and/or a bolt hole for facilitating fixation to other devices. The buckle is used for connecting to a rope-like object, for example, for a rope strap to pass through. The bolt hole is used for directly fixing the pull device to an external object, such as a wall, with a bolt.

BRIEF SUMMARY

Technical Problems

However, during practical use of the pull device for fitness exercise, the pull device needs to be fixed to different places or at different heights depending on different exercise postures or actual use scenarios. Particularly, when the pull device needs to be fixed through various gaps, such as a door jamb gap, it is very difficult to fix the pull device with the buckle and/or the bolt hole in the above solution.

Further, with the above solution as well as the existing pull device fixing apparatus, it cannot be ensured that the pull device fixing apparatus can be stably fixed at a point of the gap during the exercise carried out by the user; meanwhile, it is impossible to conveniently change the height at which the pull device is fixed.

Furthermore, it cannot be ensured that the fixing point refrains from a movement as the exercise posture of the user changes, thus affecting using the pull device anytime and anyplace, which is not conducive to popularization.
